>>What matters too is that audio systems are a Voltage based reference and not a power based reference. Frequently you see people concerned with the impedance curve.
If the system is flat with a fixed voltage drive, then it is like the recording process where X pressure equals X voltage.Could you expand on this, where does impedance based dB attenuation figure. Not sure if you are covering a different point here but given ohms law it's trivial to demonstrate that a speaker with an significant input impedance variation would suffer from audible impedance induced attenuation if driven by amplifiers with reasonably high output impedance. For example the A3 impedance curve above would suggest that attenuation would occur in the bass and the critical 3-4kHz region with obliging amplifiers, or are you discussing a different issue?
